Well I was cleaning an AR today and I noticed the gas rings look jacked up. I have been shooting this rifle and have had zero malfunctions in the past 800 rounds or so(roughly). The rifle only has about 1000-1400(roughly) rounds since new and on these rings. It's a PSA complete carbine upper if that helps, the premium one they offer. Anyways, one of the rings has a wide gap and a lot of play in it, it's either the front one or the back one, the others look fine. I assume the rifle is safe to shoot... but what caused this and is this as big of a deal as the internet says? Some people say(as if they truly know it to be true) that if the bolt won't hold the entire BCG up then you have to replace them. Others say if the bolt drops out on it's on they are worn out... then some people say to shoot it until the rifle does not function properly? What do I need to do? I wanted to shoot it tomorrow and if it makes any difference I usually run nasty under powered steel case ammo through this rifle. Is this one of the extra parts I need to keep? I need real AR advice, not internet warrior wisdom, hope that doesn't offend anyone. Seriously though, thanks for the help.
